rossore Application filed February 3, 1968, Serial o. '114.096,

T0 all 'Pf/mmt may corn-ern Be i known that l., FREEMAN R. lVrLiisox,Jr., citizen of the United residing :it liorthingron, in the county ofFinnlolin and tale or" Ohio, lieve invented oerein new and usefulImprovements in Conveyer- Belt Supports, of which the following is sspecification, reference being had therein to the accompanying drawing.

My invention relates to conveyer belt supports, and has for its objectto provide an improved troughing mechanism, and' irnproved means ofmounting the belt support as Ae. whole.

The guide idlers illustrated in the drsw ings of this application aredescribed .fi-ncl claimed in my fao-pending application Ser. No.761,784, filed April 17, 1913.

In the drawings, Figure 1. is a side eleva.- bion of one group of bell;supporting pulleys, Fig. 2 is a plan View of the .se-me. Fig. 3 is eView in elevation of s modified form of construction. Fig. 4 is a Viewin side elevation showing several sets of pulleys'. Fig. 5 is an endelevation of the bracket 28. Fig. 6 is a, plan View of the tubularcasting Fig. 7 is a Vertical section along the line 7-7 of Fig. 2.

In the drawings, 1-1 indicate Channel beams bolted et. their ends to thestringere 242 by means of the castings 3 3 and bolts {il- 4 and 5-5securing the channels to the casting and the casing to the stringers. t

Carried by vthe channels 1-l are the tubular castings 6-6, having thefour' arms 7-7 and 8K8. The arms 7--7' enter holes in the webs of theChannel beams, and the internally serew-tlxreaded capped nui; 9 engagesthe projecting end of the erin 7, and the threaded projecting end of'the opposie erin 7 carries the internally threaded thinr ble,10,'whichin turn supports the grease @up 11. The other arms 8-8 are tapped ioreceive toe hollow shafts 12 and 13. The shaft i2 is mounted et n.considera-ble. inclination to the horizontal and the shaft 13 at enangle more nearly npproeching the horizaon- 'tal Upon the shaft' 12 ismouned the "mlley 1.4, which is free to rotate thereon being held inposit-ion longitudinally hy the boss 15 of the tubular casting, whichasis as en end-thrust bearing. The washer 1,6 is interposed between thisboss and the end of the huh 17 of the pulley.

The two hollow shafts 1`3-13 are con l. .1 To rhs onsi he holioiiTsha-fis it-l2 ere .sled me tubular castings f3--20, each therein eright-angle bend 2l. nto the `@einer end of each. of these pipeezisrings is screwed the hollow shft 22, upon which is mounted the guideidler puly ley 23. A nut 24 upon the eind of each of these hollow shaftsxes guide pulleysl 23 in position. llie rounded upper ends of the. guidepulleys urherrnore provide e ver considerable aid in .nhs-ring the heltafter 'it has passed through n ripping.; mechanism and prevent the edgesofthe belt from beeomihg frayed from Contact with upper ends oi he usualtype of guide idler pulleys.

The peripl'lerel surfaces of the pulleys 23 nre provided with e roundedtaper at their i upper ends to facilita te the elevation of the beltfrom lzronghing pulleys 13 and 14, when trai ing ripping device isemployed to incline he heit transversely for iinloading materiel. intobins or other receptacles,

et s number of points along the pelli of the conveyer.

By reason o the eentral, verticel Wall 18 in the cont-er esst-ing 18,lle spgee within the hollow shafts and connecting pipe castings 'isdivided into two continuous lubricantholding chambers, which are fedeach from one of, lhs egress" .oups v1l. The lubricant under pres-.f D

is forced into :ill ps1. shaicingr, through lhe luhfleent- Channels 25to the wenrinf7 `nrfnoes of he pulleys. The rel-urn Miller pulleys 26are carried by fr 2, lo which they Aire rigidly atwhich is in turnsuspended in he bearing hrzxfxlnrs hung from the horizontnl holle 25),extending across from channel lo channel. Alnvli bracket is cored as at31 to provide a. lubricant duet, leading:` from the square re hrn thespring-pressed' Gzip o1 the hol-low' the threaded aperture into which isthreaded the grease cup 33, to the hearing socket 33. These relurn idlerpulleys nre preferably oniit'i'ed from alternatetroughing idler frames.v y

llerelofore hraelzet snndards bolted to the upper side of wooden ormetal girders have heen used to support.

These rails, whichare designed to guide the traveling belt tripper as it-moves from one position of adjustment to another,A are clamped upon thechannels bymeans of the clamp plates 35, whichare drawn-toward cachother by the bolt-36 andnu.. 37, in such a way as to wedge the taperedbase of the rail to position. This casting is provided with the slottedholeA 38, through which the bolt 4t passes.
